This delightful article by Maria Blees slipped by me during my most recent blogging hiatus. It presents a handy framework to run unit tests on native code, some macros to hook you into VSTS code coverage, and some excellent guidance on the reality of testing and refactoring. It also recommends some nice resources. (How fun is it to read a plea (in a pdf she recommends) for designing to be testable and not to put real code in your event handlers, then realize it's from six years ago?) If you write C++ code, go read this article now. It has plenty of real meat in it, and concludes with this paragraph:

My goal has been to show that unit testing native C++ can be easy, fun, and you can get started right now. To give you an idea of the power of WinUnit, take a look through the TestWinUnit project, where I used WinUnit to test itself. Those examples are completely real world and will show you advanced usage you can apply to your own unit tests. If you've been struggling with your native C++ unit testing, WinUnit makes it easy—and any time you can make testing easy, you're far more likely to actually do it.

Mission accomplished, Maria!
